13 Claims.

The invention relates to new and useful improvements in razors, and more particularly to novel and useful improvements in an encased magazine razor openable for use and completely collapsible into and contained within its casing when not in use.

Objects and advantages of the invention will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice with the invention, the same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.

The accompanying drawings, referred to herein and constituting a part hereof, illustrate one embodiment of the invention, and together with the description, serve to explain the principles of the invention.

Objects of the invention are to provide a very compact shaving utensil comprising a casing which when closed includes the blade and handle in a smooth compact envelope, these being simply and readily movable and projectable into shaving position and in like manner retractable again within the casing; to provide such a casing so shaped and disposed in connection with the projected razor blade to form a support and guide coacting with the face of the user while shaving; to provide such a device wherein movement of the handle from retracted position to operating or shaving position will automatically project the razor from within the casing out to shaving position, the reverse movement of the handle automatically retracting the blade into the casing, leaving the exterior of the casing closed and smooth; to provide a support for the blade carrier whereby it may be presented outside the casing, as for cleaning, and then restored into its usual position within the casing; to provide also within the casing a storage for blades, which is preferably a container slidable into and retractable from the casing, and having detent means for holding the handle in its stored position within the casing.

Referring now in detail to the embodiment of the invention illustrated by way of example in the accompanying drawings, a casing I is provided, preferably of relatively flat and elongate form and also preferably of rounded, fiat crosssection. Disposed longitudinally along one of the narrow sides of the casing is an elongated slot I extending substantially the full length of the casing, and through this slot a blade carrier 2 is projectable from the easing into shaving position and is retractable into the casing for storage. The blade carrier 2 is of general plate-like form, as shown in Fig. 4, and along its front side it has a seat 2 for a razor blade 5, the blade fitting within the seat. At its front edge the carrier 2 has a longitudinally-disposed turned over lip 2 on which are formed guards or stops 3, which engage with the front edge of the blade to position it, and they also act as guards while shaving. A back stop I2 extends along the rear of the blade seat and the back edge of the blade fits against it. The blade has a central aperture 5 adapted to fit over a positioning lug 4 which extends upwardly from the blade seat 2 Means are provided whereby movement of the handle between its storage position and its operating position automatically projects the blade carrier and blade for shaving, and retracts them for storage, and comprises a cam slot I3 formed in the rear part of the blade carrier 2, the parts 00- operating therewith being later described.

In accordance with one feature of the invention, the blade carrier may be moved outside of the casing, as for instance, for thorough cleaning although, so far as concerns the broader aspects of the invention, this feature may be omitted. Means to that end are included in the present embodiment, comprising a support for blade car-.

rier which is insertable into and slidable in and out ofv the casing at one end thereof, but preferably not detachable, and the blade carrier, as embodied, is carried in and out with this support, and also is slidable on this support during its movement between storage position and shaving position. As embodied, a plate Ii is slidable into and out of the casing through a transversely-extending slot 22 formed in a fiat end 22 of the casing I. Said supporting plate 6*- is slidably supported in the general inner frame 23 (Fig. '7) which is mounted in fixed position within the casing I. For this purpose frame 23 has a plate 25 extending both along and across substantially centrally of the casing I. In plate 25 are formed longitudinally-disposed, recessed guiding grooves 26 into which fit corresponding longitudinally-disposed, projecting guides I5,

- formed on the underside of the support 6 whereby the support is slidable on frame plate 25 into and out of the casing. Onthe outer end of the support 6 is a finished plate 6' which fills the slot 22 in the closed position. If this support be dispensed with, the casing may be openable and the blade carrier be, lifted out and reinserted.

The mounting for they blade carrier to permit the transverse movement thereof upon the support I5 between shaving and stored positions comprises turned-over guideways IT formed at either end of the plate 6*, within which the ends of the plate 2 slide transversely. Lugs I6 are formed at the innerend of the plate 6? to prevent total withdrawal thereof from the casing I; A longitudinally-disposed slot I4 is formed in the plate 6 to perm-it the handle 8 to connect with slot I3 in blade support 2 to effect the projecting and retracting movement of the blade carrier.

Referring now to the storable and withdrawable handle mechanism, a longitudinal slot 20 is disposed along one of the broad sides of the casing I, and a corresponding slot 20 is formed in-theframe 23. A hollow handle 8, of rectangu lar cross-section has a rounded head 8*, from which projects at either side cylindrical pins 35; which pins are adapted to slide along guideways 28-, formed at either side along the edges of the slot 28%. Located centrally along the guideways 28 are two projecting tongues 29, and in the pins 3.5.areformed recesses 36. When the handle 8; is swung out from storage position in slot 20' to the perpendicular position, as shown in Fig. 2, and is slid along the guideways 28, the tongues 29 will enter the apertures 36 and centrally position the handle in the perpendicular position, and

hold it there for shaving and until the handle is slid backwardly along the guides 28 preparatory to being swung down into storage position.

The embodied means whereby the handle during its movement from storage to operative position automatically projects the blade carrier 2 comprises a pin 33 projecting from the hub 8 of the handle, and as the handle is brought from the storage position to the perpendicular operating position; the pin 33 passes through a slot 30 in plate 25, through slot I4 in the supporting plate 6*, and engages with the curved cam slot I3 in blade carrier 2, and during the sliding movement of the handle 8 along the guideways 28 until stopped position by the tongues 23, the blade carrier is projected by the action of pin 33 sliding in slot I3 to the shaving position as shown in Fig. 2. Upon the reverse movement of the handle back to storage position, the blade carrier is retracted in like manner. The handle is extensible for shaving and contractable for storage and to this end comprises a rectangular hollow outer member 9 which is free to slide on member 8. The member 8 has a slot II in the side thereof, and the member 9 has a projection III extending into slot II, which serves as a stop. For the purpose of holding the handle in the storage position, the handle member 8 has an apertured end 31 with which engages a detent stop 3|.

In accordance with one feature of the invention, storage for a supply of new blades is provided within the casing, and as shown, a space 24 is provided within the frame 23 for that purpose. Preferably a blade container or magazine 32 is utilized as a carrier for the blades, the carrier being slidable into and out of the space 24. A slot I9 is formed in the fiat end 22 of the casing I, through which the blade magazine 32 is slidable into and out of the space 24. The carrier 32 is provided with an end plate I which in the closed position abuts against the end plate 22 of the casing. In this form the handle detent 3| is conveniently mounted on the plate I, and projects through a slot I8 into the interior of the frame to engage with the hollow end 31 of the handle member 8 as it lies Within the slot 20. thereby holding the handle in the stored or closed position. When in this closed position a lug 34 on the hub 8 of the handle extends through slots 38 and I 4 into slot I3, and holds the parts locked in stored position.

In Figs. 11 to 18 is shown another embodiment having simpler mechanism and of considerably less size. In this embodiment the endwiseslidable carrier for the transversely-movable blade support is dispensed with, and the casing is openable for the purposes of cleansing and blade-changing, and the form of other parts is modified to suit the different construction. The same reference numerals are applied to the same parts. In the present embodiment of this compact and simplified form, the casing I comprises two longitudinal halves I and I which are openable along a hinge 40, and are held firmly closed by spring snap fingers I The transverselymovable blade .carrier 2, which is projectable and retractable by the pivotal and slidable movement of the handle 8, 9, as previously shown and described, is mounted directly upon the platelike frame member 25*, and the guideways I"! in which the blade support moves transversely are formed on either end of this frame plate 25 the blade support being mounted directly upon and slidable over plate 25 the blade carrier 2 being projectable from and retractable into the slot I.

The handle is the same or substantially similar to that previously shown and described, and operates in the same manner to project and retract the blade support and to fold into the casing, being held in the casing by a friction or snap fit. In this case when the handle is rocked, the pin 33 passes through the slot [4 in the frame plate 25 and engages with the slot 13 to move the blade support during the sliding action of the handle to the central position which it occupies for shaving. As shown in Fig. 1'7, in this embodiment the head of handle 8 is provided with the flat extensions 35 which are adapted to revolve in circular recesses 31 adjacent one end of the frame member 25 when the handle is to be moved from the recessed position, and to slide along groove 38 when the handle is moved to the central portion of the casing I which is the shaving position.

Ample blade storage is provided within one part of the casing, as shown in Fig. 18. Pivoted on the hinge pin 40 is a flat plate 4| of approximately the area of the inner face of the half casing, and integral with or joined to the ends of plate 4| are two segmental plates 42 and 43 of approximately the shape and size of the end plates of the half casing. A snap fastening 44 may be provided to hold the parts closed. The blades are stored within this space and are accessible when it is opened as shown in Fig. 18.

This form presents a complete and very small and compact collapsible razor, with all the parts connected together, without separate or detached parts that must be screwed together and unscrewed or otherwise fastened and unfastened, which is simply and readily openable for cleansing and blade-changing without removal and replacement of detachable parts, and which has ample blade storage.
